Art historians think the upper part of the statue on the right was actually a sculpture of Sapho. Also, if you look closely at the figure on the left, a female breast has been added to what appears to be a male torso with the head of Apollo judging from the knotted hair style. If the restorationist had completed the sculpture of Sapho with a female lower torso and left Apollo as male it could have quite logically represented a version of Apollo and Daphne.
